-
Paragraph 0062, (2018/09/20)
The present invention concerns acontinuous-flow process for the production of allyl compounds by deoxydehydration of glycerol comprising the following steps: (a)Forming a reactive solution by mixing glycerol (1) with: ?a carboxylic acid (2), and/or ?a triethyl orthoester, preferably triethyl orthoformate (TEOF); (b)Feeding the reactive solution to an inlet of a channel of a thermolysis microreactor module wherein the channel has an inner hydraulic diameter, D=4A/P, wherein A is the area and P the perimeter of a cross-section of the channel, of not more than 1000μm, (c)Exposing the reactive solution to thermolysis by driving a flow of the reactive solution along the channel from the inlet to an outlet, for a thermolysis time, t, at a pressure, P, and at a thermolysis temperature, T, larger than 200°C, to form thermolysis products including at least one allyl compound; and Recovering the thermolysis products at the outlet and separating the at least one allyl compound from the other thermolysis products
Method for preparing formate-type compound

Paragraph 0039; 0047; 0048, (2018/07/30)
The invention discloses a method for preparing a formate-type compound. The method comprises the following steps of: adopting an alcohol-type compound and 1,3-dihydroxyacetone as reaction raw materials, and under the existence of a composite catalyst and an oxidant, reacting for 2-48 hours in a reaction medium in a reactor at a reaction temperature of 25-100 DEG C so as to obtain the formate-typecompound. The method disclosed by the invention is simple, and is mild in reaction condition, and by the method, a target product can be obtained by low cost and high yield; the used catalyst has highcatalytic activity, and is easily separated from a reaction system to be repeatedly used; the whole process is environment-friendly, and the reaction raw material (1,3-dihydroxyacetone) is easily converted from a side product (glycerol) of biodiesel, so that the utilization of the glycerol is promoted.

The deoxydehydration (DODH) of glycerol towards allyl alcohol was revisited under continuous-flow conditions combining a microfluidic reactor setup and a unique reactive dynamic feed solution approach. Short reaction times, high yield and excellent selectivity were achieved at high temperature and moderate pressure in the presence of formic acid, triethyl orthoformate, or a combination of both. Triethyl orthoformate appeared as a superior reagent for the DODH of glycerol, with shorter reaction times, lower reaction temperatures and more robust conditions. In-line IR spectroscopy and computations provided different perspectives on the unique reactivity of glycerol O,O,O-orthoesters.
A Method for Preparation of Allyl Formate
-
Paragraph 0027; 0028; 0029; 0047, (2016/10/10)
The present invention relates to a manufacturing method of allyl formate and allyl formate manufactured thereby, for reacting at reaction temperature of 220-250°C by inserting 5 to 10 equivalent weight of formic acid, with respect to 1 equivalent weight of glycerol. According to a manufacturing method of allyl formate of the present invention, a conversion rate, selectivity, and a yield of allyl formate can be significantly increased by using special synthesis condition.

Page/Page column 4; 5, (2015/09/23)
Disclosed is a method for preparing allyl alcohol, wherein glycerol and formic acid are reacted under specific synthesis conditions, thus remarkably increasing the concentration of allyl alcohol in the liquid reaction products and minimizing the production of allyl formate byproduct and the production of unreacted formic acid.

A method of synthesis of allyl alcohol from glycerol, whereby allyl alcohol is produced at a yield of about 80% or greater. The method comprising the heating of a reaction mixture of glycerol and a carboxylic acid under an inert atmosphere and distilling allyl alcohol from the reaction mixture.
PROCESS FOR PREPARING ACRYLIC ACID
-
Page/Page column 16, (2008/12/07)
A process for preparing acrylic acid, in which an acrylic acid-comprising product gas mixture obtained by catalytic gas phase partial oxidation of a C3 precursor of acrylic acid is fractionally condensed in a condensation column provided with internals ascending into itself with side draw removal of crude acrylic acid and with liquid phase draw removal of acrylic acid-comprising acid water, and acrylic acid present in acid water is taken up into an extractant and then removed from the extractant and recycled into the condensation column, or taken up in aqueous metal hydroxide, or sent to further purification of the crude acrylic acid.
